Chapter 4. Verifying OpenShift Data Foundation deployment
Use this section to verify that OpenShift Data Foundation is deployed correctly.
4.1. Verifying the state of the pods
Procedure
-
Click Workloads
Pods from the OpenShift Web Console. Select
openshift-storagefrom the Project drop-down list.NoteIf the Show default projects option is disabled, use the toggle button to list all the default projects.
For more information on the expected number of pods for each component and how it varies depending on the number of nodes, see the following table:
Set filter for Running and Completed pods to verify that the following pods are in
RunningandCompletedstate:NoteThe available pods depend on the cluster configuration. When the cluster is deployed as a standalone Multicloud Object Gateway, the
rook-ceph-operator-* pods are not available. Similarly, when the cluster is deployed without the Multicloud Object Gateway,noobaa-* pods are not available.
| Component | Corresponding pods |
| OpenShift Data Foundation Operator |
|
| Rook-ceph Operator |
(1 pod on any storage node) |
| Multicloud Object Gateway |
|
| MON |
(3 pods distributed across storage nodes) |
| MGR |
(2 pods on different storage nodes, one active, one standby) |
| MDS |
(2 pods distributed across storage nodes) |
| RGW |
|
| CSI |
|
| rook-ceph-crashcollector |
(1 pod on each storage node) |
| OSD |

4.2. Verifying the OpenShift Data Foundation cluster is healthy
Procedure
-
In the OpenShift Web Console, click Storage
Data Foundation. - In the Status card of the Overview tab, click Storage System and then click the storage system link from the pop up that appears.
- In the Status card of the Block and File tab, verify that the Storage Cluster has a green tick.
- In the Details card, verify that the cluster information is displayed.
For more information on the health of the OpenShift Data Foundation cluster using the Block and File dashboard, see Monitoring OpenShift Data Foundation.
4.3. Verifying the Multicloud Object Gateway is healthy
Procedure
-
In the OpenShift Web Console, click Storage
Data Foundation. In the Status card of the Overview tab, click Storage System and then click the storage system link from the pop up that appears.
- In the Status card of the Object tab, verify that both Object Service and Data Resiliency have a green tick.
- In the Details card, verify that the MCG information is displayed.
For more information on the health of the OpenShift Data Foundation cluster using the object service dashboard, see Monitoring OpenShift Data Foundation.
To avoid data loss, it is recommended to take a backup of NooBaa DB PVC regularly. If NooBaa DB fails and cannot be recovered, then you can revert to the latest backed-up version. For instructions on backing up your NooBaa DB, follow the steps in the knowledgebase article, Perform a One-Time Backup of the Database for the Multicloud Object Gateway.
4.4. Verifying that the specific storage classes exist
Procedure
-
Click Storage
Storage Classes from the left pane of the OpenShift Web Console. Verify that the following storage classes are created with the OpenShift Data Foundation cluster creation:
-
ocs-storagecluster-ceph-rbd -
ocs-storagecluster-cephfs -
openshift-storage.noobaa.io -
ocs-storagecluster-ceph-rgw
